. More forgiving - Each time you attach a core you reset to that point when you lose. Plus, a new countdown starts for each core. With GLaDOS the clock had only one countdown and if you lose you need to start from the beginning.

. It's easier to get the cores - in the original Portal the final core especially took some skill to access. In Portal 2 the game basically trained you how to do everything, and they're all located in roughly the same spot, except the final core. Like I said though when the speed gel is released the solution to getting it is ludicrously obvious, and because you're jumping straight upward instead of flinging it's ridiculously easy.

. Hitting Wheatley is incredibly easy. To get the bombs to hit him all you need to do is plant a portal in front of you, plant another one at a spot where he doesn't have his walls set up, and just stand there. In the original Portal GLaDOS moved around a lot, and you needed to make sure that the rocket was sent at the correct angle to hit her.

To be honest it was really the only disappointing part of a truly great game. I was all ready to write off the ending as being underwhelming and undeserving of the rest of the game. Then the portal to the moon scene happened, and my faith in humanity was restored. Oh Portal 2, how could I ever have doubted you?

I finished Glados in Portal 1 with nearly three minutes to spare on my first try... but I did have the benefit of seeing my friend finish it a few hours earlier. I would probably have wasted a minute or two figuring stuff out without that.

Wheatley in Portal 2 took me two tries because I had no clue what I was supposed to do on my first attempt. Getting the location and timing right to catch the green/second core was the most troublesome part of that fight for me.
